6083716666

The Caller ID belongs to Nomorobo.  When a call is blocked by Nomorobo, the caller has an opportunity to respond to a captcha.  (Random number they have to respond to in order to prove they are a person rather than a recorded message.)  If they respond correctly, Nomorobo forwards the call using the CID 608-371-6666 *regardless* of the caller's actual area code or number.  So, a caller from Illinois (for example) could be displayed with this Wisconsin area code.
I don't know if Nomorobo is able to determine the difference between their own outgoing call and a robocaller spoofing their number.
The way I see it, if it's worth the time for the caller to enter the captcha, then they should be willing to take the time to leave a VM.  So, I don't answer.  If they don't leave a message, it couldn't have been that important.

I use NOMOROBO too... Got through after first coming from 2124636279 (Engine Group)

So 608-371-6666 is actually NOMOROBO, basically when a person calls your line they get intercepted by NOMOROBO.  The telemarketer gets a message to enter a CAPTCHA numeric code, if they answer correctly, they get re-directed back to you using the NOMOROBO number.  So usually you'll get a call from the telemarketer, it stops after 1 ring, and then a few seconds later the 608-371-6666 calls you if they answer the numeric code correctly.  NOMOROBO stops robotic calls pretty reliably, but if they have a live person they can bypass NOMOROBO.

Received a call from this # and the voice mail they left said to call back at 877-366-0014 which is a debt collector.  They left no name as to who they were calling

Keeping calling my house.  I don’t answer, but the caller ID says SSI

Rude, once you tell them to never call back they start cussing at you. We have call blocking, now we won’t have to them any longer

Similar to others, the "perp" called 5x in 2 mins.  Nomorobo "grabs" it after 2 rings.  Tedious, though, to listen to that ringing.  My voice provider (COMCAST) needs to step up their "game" and give us more control.

What you're receiving is a redirect from NOMOROBO.   The original call gets redirected from you by nomorobo and then is picked up by nomorobo with a message to enter a code.  If the code is entered correctly, nomorobo redirects the call back to you but with the 608-371-6666 phone number.

It's not a robo-call, it's a call center with an (insert obscene/profane words here) idiot calling you manually.  The longer you can keep the caller on the line, the worse his/her performance will be at the call center.  This will be reflected in her/his pay for the day.  If you're lucky, they'll get fired for poor scamming performance.

I don't answer the call.  It goes directly to answering service.  They leave no message.

These are CRIMINALS, trying to steal your identity.  I'd like to know their carrier as the history shows that this number has been used for YEARS with a myriad of different criminal activities and lies, trying to get our personal data.  The carrier should be prosecuted for promoting and being complicit in criminal activity.

Nice!  That's awesome.  Getting them back like that.  Same thing happened to me, but I didn't block the calls.

Oooooh, be careful if they speak poor English and have a strong accent.  I heard those calls could come from other countries and they could put the bill into your account for the call.  That's what I've heard.  So to pass it on.  If I answer calls with that kind of strong accent, I hang up, immediately.  Now, it comes to a point that I don't answer the phone to ANYONE unless the number is familiar (landline or home number).  OR I don't have voicemail (cell phone).  And I only give my cell number to text, I tell them not to call.  I might give places like work and school (though I am no longer in school) both numbers, and other places my home number only.

I've gotten one of those kinds of calls too; I didn't answer it, either.  IF it's an important number, they'll leave a VM.  If they call my cell, than I know its a hoax, because I don't give out my cell number to people I don't know.

TRUE!  If they start cussing at you, then you know that its a bad call.  Because if it was from a real company, they HAVE to be pleasant, whether you get nasty to them or not!  Some call blocking doesn't work; they only lasts a few months and then it reverses back.

I received a call from this number yesterday.  Today, I noticed four more calls.  They must be using nomorobo's number to  try to get through.

Charles calling about Medicare program. Telemarketing scam.

This caller is the worst irritating caller.  I wish this caller should be taken care of.

aid he was from ? Insurance agency. Told him premium is paid what do you want, I'm busy. Said records show we owe 60K on our mortgage. Told him we don't have a mortgage. He said that's what I needed to know and hung up.

Called today 1:37 pm. No message. Got around NoMoRobo because they have a live caller and can bypass the NoMoRobo block. See website for explanation.

Just a robo call, spammer hang up caller.  I'm not connected with any sort of sleep disorder or anything else listed in this call history.
